DC/AC Hermetic Distribution Board Emiter EM-588_DCAC (3-phase, 2 MPPT)

The Emiter EM-588_DCAC hermetic distribution board is a ready-to-connect solution designed for three-phase photovoltaic installations with two MPPTs. The product in a surface-mounted enclosure with an IP65 protection rating is equipped with protective devices, Type 2 Dehn surge arresters, and external panel-mounted MC4 connectors.

The Emiter EM-588_DCAC PV distribution board is designed for surface mounting in installations with or without an isolated lightning protection system. The Class II protection PHS 24T enclosure provides an IP65 protection rating and IK08 impact resistance. Inside, halogen-free plastic and a transparent inspection door are used. The fully wired modular design facilitates the quick connection of two module strings thanks to the routed panel-mounted MC4 connectors.
